>Description:

This patch adds  a basic infrastructure support for building binaries for
debugging purposes.  A new knob, WITH_DEBUG is introduced.  If set
DEBUG_FLAGS (-g at default) are added to CFLAGS and binaries
doesn't get stripped by INSTALL_PROGRAM.  Besides, each port
could/should add its specific things for WITH_DEBUG.
DEBUG_FLAGS can be overridden, of course.
